of the crane.

. position.

clear, and exact descriptionthereof, which will enable those skilled in the art to make Land use the same, reference being had to the accompanying drawings, forniingpart of this specification. i

This'invcntion relates to a new and improved device for elevating and handling evaporating-pansg` and the invention consists inV attachingthe pan to a crane, whereby it may be raised and lowered by al lever, and otherwise moved to and from the arch or furnace, as may be desired', as will hereinafter be described.

The drawingrepr-esents an elevation of the apparatus, with an evaporating-pan attached v Similar letters of reference indicate corresponding parts. v I

A represents the frame by which the crane is supported.

B is the standard of the crane, which is Iattached to the -frame A by pivots at its ton and bottom ends, upon which it freely turns. j l

C isthe arm of the crane, and l,

D is the brace, attached thereto by belts, or in any substantial manner.

The arm and brace are attached to the standard by metallic fastenings, (E and F,) whichfornrrnortises for the standard', which mortises contain friction-rolls, seen at a in the drawing, which rolls bearragainst the standard, and allow the armto be raised and lowered,.or moved up and down, without friction.

G represents the pan, which is' suspended from across of four arms, which rests upon the top of the arm C H is this cross, and

J represents its fourarms. v

lo represents the four hooks or rods by which the pan is suspended.

represents the handles (two o n each side of the pan) to which the hooks c are attached.

L is a lever,'which passes through aI mortisc in the standard of the crane, as seen at m.

N is an evener, which is attached to the short end of the lever, as seenV in the drawing.

The evener'N is connected with *the four Varmsof the cross H, by rods, in such a'nianner that the arm of the' crane and the pan a're rased'vcrtically, by being properly balanced from the end ofthe lever by the evener N and the rods connected therewith. l A` 1 For the proper adjustment of these rods, they are connected with the blocks o, on'the top of the arms J, which turn on pivots, the pivots being the Shanks ofthe eyes which pass up from the underside ofthe arms, to which eyes the suspensionrods [c are attached.

pp are two short'rods, connected withl the vends of the evener,`fr on1 leach of which extend two rods p', which branch o'` to the fourni-ms of the cross, which rods are attachedV to the blocks o, as seen in the drawing.

R is a hook, attached to the lever L, which, when' the pan is raised from the arch, as seen in the drawing, is hooked into a'staple in the armof the crane, as seen,'so that the pan is thereby held vup from the arch.

i There are also holes for a rest-pin inthe standard B, so that the brace ofthe arm may rest on apin inserted, which'pin'nay sustain the weight of the pan whenit is raised from ythe areh, .or when inlany other desired Having thus described our invention, we. claim as new, and desire to secure by Letters Patent- ,1. The evener N, rods h t h h, cross H, in combination with' arm C, and brace D, lever L, and standard B, arranged substantially as and for thepurposes herein set fort Y 2. The pan G, in combination with the hooks k kk 7c, cross H, substantially as and for the purpose specified.
